Hello and I wish you a warm welcome to Andy Devey's website THE SOLAR EXPLORER a site as dynamic as our Sun. I am continuously evolving this site as an interactive resource for you aspiring amateur astronomers that are committed to SAFELY achieving your own progressive solar astronomical and outreach goals. Please feel free to contact me to arrange a visit or to ask questions or make any comments about my website - all feedback is helpful! Check out this short video [2 - 1/2 minutes] prepared by the local Barnsley press. HERE IS MY LATEST WORK and here is the most active region to date. Missed that major solar event? HERE ARE MY LARGER HIGHER RESOLUTION MOVIE FILES and my tutorial 1tutorial 2tutorial 3, How to measure solar features and my latest photos. I use The Image Source DMK21 and DMK51 monochrome cameras. TRANSIT OF VENUS 5 & 6 JUNE 2012 - HERE IS THE SDO DATA and my work using the GONG data. FOLLOW ME ON TWITTER @AndyDevey NEW work on AR2192. My ASTROBIN page for very large files

Here are over 140 online TV programs/talks and videos about the Sun dating back to the 1950's and over 610 books and substantive papers and discoveries about the Sun/Solar Astronomy and observational advances dating back to the 12th Century! Here is the latest Solar DATA from the science community. Would you be interested in sponsoring me and to help me to further develop my work?

X2.0 flare 27 October 2014

27 October 2014 here is an X2.0 class solar flare [one of 3 X-class flares] that I caught from AR2192 sequence from 14:21 to 15:36 UT

in variable seeing here is the full size movie and a link to the other flares and full disc images that I caught from this huge active region

between 17 and 30 October 2014

1 July 2014 here two consecutive ribbon flares a C6.0 and a M1.4 class event break across the AR2106 and AR2102 regions between 10:00 and 12:46 UT in reasonable

seeing conditions. These almost parallel structures span an area the size of Jupiter during their flash phases as they react with the filaments. Full size version here!


12 March 2015 here is one of my full disc animations showing an M1.4 class flare from 12:05 to 13:05 UT.

9 February 2015 one million kilometre solar filament and more images including full sized versions


23 February 2014 the Sun presented post flare loop structure this sequence runs from 10:16 to 12:00 UT [104 frames] seeing was reasonable grade 1 to a poor grade 3.

11 September 2013

11 September 2013. Here a huge prominence lifts off from the south-east limb between 08:07 and 09:23UT in grade 1 to grade 3 seeing conditions. The image should be rotated

120 degrees counter clockwise for correct solar orientation.

25 October 2013 the seeing was poor but this is my first capture of an X-class flare here an X2.1 breaks over AR1882 from 14:54 to 15:42UT - a goal realized!

3 September 2011

3 September 2013 here is a 5-hour look at a rotating prominence on the south east limb between 10:07 and 15:07UT the seeing varied from a reasonable grade 2 to a poor grade 4.

I was at 3.2m focal length and suffered 5.2 degrees of field rotation between the first and last frames hence the moving lower edge of this video.

5 June 2013

5 June 2013 here is a high resolution view of a M1.3-class solar flare breaking over AR1762 from 08:47 to 10:07UT in reasonable seeing.


23 June 2013 here is my most successful attempt at capturing solar granulation from 07:49 to 08:39UT. These convection cells are about 1000km in diameter

and at this scale I am at less than 100km per pixel on the surface of the Sun that is at a distance of about 150,000,000 km distance.

5 January 2013

5 January 2013 here a new active region is rolling around the north-east limb and signals its arrival with a beautiful loop,

image from 11:45 to 12:53UT in grade 1 to grade 2 seeing conditions - a good start to the new year?

Large mosaic photo 3 March 2015.

Here is a CaK disc

12 September 2013

12 September 2012 here is a look at a surge prominence from AR1564 as it traverses the south-west limb between 09:35 and 10:31UT in grade 1

to grade 2 seeing conditions.

4 Sept 2012

4 September 2012 here a huge prominence lifts off the north-west limb between 08:48 and 12:28UT in grade 2 to grade 3 seeing conditions.


Here is an M3.7-class flare that broke across AR1302 between 15-27 and 15-39UT on the 25 September 2011. The image shows my full sequence from 15-12 to 15-39UT, you can clearly see a loop fails and this triggers this huge side blast and ejection.  Interested in capturing and measuring solar flares? NEW - Please check out the new 32-minute DVD on Lets Talk Astronomy featuring some of my solar work.

Here is a spectacular post flare loop structure that I caught after an M7.7-class flare broke across departing sunspot AR1520 on the 19 July 2012 sequence between 08:56 and 10:40UT in grade 2 to grade 4 seeing conditions I used a standard PST at 1.6m focal length.

Below is a huge [20 mb] lunar photo about 3m x 3m in size, click on this full sized link and scroll down and across to the right to take a close-up tour of the battered lunar surface!

This is the largest photo of the Moon that I have made this far.

7 March 2012

Here is a Huge X5.4-class solar flare, I have been given permission by the NSO in the US to use their data from the GONG network to make movies of the major solar events. Here is the link to my page featuring these major events.


Here I am starting to experiment with high resolution white light photography at long focal lengths using my Takahashi TOA130 refractor and a Lunt Herschel wedge I use Barlow lenses to increase the focal length to 4m. I am trying to capture the penumbral material flowing down into the umbra - the core of the sunspot. The photo above is the core of the leading sunspot AR1775 on 25 June 2013 between 07:49 and 08:19:UT in grade 1 to grade 2 seeing conditions.

Here is my first capture of a Moreton wave a solar shock wave emanating from a M2.0-class solar flare, they are like the ripples when throwing a stone into a pond. I was using a standard PST at 0.8m focal length to capture this one. Sequence from 10-33 to 11-41UT in seeing grade 1 conditions.

4 March 2012

Sometimes these magnetic filaments erupt here is one that I caught with my PST on the 4 August 2012 between 12:18 and 13:27UT in grade 2 seeing conditions. This filament was over 500,000 miles long.

4 August 2012 b/w

Here I was filming a large active region when a plane shot through my field of view.

7 March 2012 plane transit

If you have any specific areas that you wish to improve on with your solar astronomy then please contact me through the contacts section at the bottom of my site menu and I shall respond to you directly. I will also draw together any common requests and build these answers/suggestions into some of my future tutorial sections. Here are all the web links that I have compiled should the main menu be playing up.

Please stay happy and healthy, I wish you clear skies.

Best regards

Andy Devey

NEW please check out this new DVD that you can also watch on line Lets Talk Astronomy - here I do a 25 minute interview and presentation with Dennis Ashton on SAFE solar astronomy and outreach techniques. This 32 minute program features many of my stills and coloured animation sequences together with practical tips on how to make progress - enjoy!
